Oye...does that mean that when he grows up he may not really be a viable candidate to breed?
it depends on how you feel about it. If he stays "wobble light" then you may consider breeding him. There are some breeders that refuse to work with the spider gene because of the possibility of wobbles. It can change as the animal ages, some lose it some get way worse. You really just have to read your animal.
Keep in mind that wobble-light animals can produce wobble heavy ones and vise versa.

Not necessarily... all spiders are prone to wobble, and some will even say there's no such thing as a "wobble-FREE" spider. So if you want to breed this morph, I don't think a minor wobble makes much of a difference. I plan to breed Vinnie (probably with a pastel/SP) eventually, unless his wobble ends up being a noticeable handicap.
